ISO Sensitivity
The higher the ISO sensitivity, the less light needed to make an
exposure, allowing faster shutter speeds or smaller apertures, but the
more likely the image is to be affected by noise (randomly-spaced
bright pixels, fog, or lines). Noise is particularly likely at settings
between
Hi 0.3
and
Hi 5
.
A
Hi 0.3–Hi 5
The settings
Hi 0.3
through
Hi 5
correspond to ISO sensitivities 0.3–
5 EV over ISO 51200 (ISO 64000–1640000 equivalent).
A
Lo 0.3–Lo 1
The settings
Lo 0.3
through
Lo 1
correspond to ISO sensitivities 0.3–
1 EV below ISO 100 (ISO 80–50 equivalent). Use for larger apertures
when lighting is bright. Contrast is slightly higher than normal; in most
cases, ISO sensitivities of ISO 100 or above are recommended.
